[Diagnosis of sexually transmitted diseases in Chilean pregnant adolescents].

We searched in 100 healthy pregnant women by isolation, the presence of Neisseria gonorrhoeae, Herpes simplex, Mycoplasma hominis, Ureaplasma urealyticum and Chlamydia trachomatis. Blood was also taken for examination of specific antibodies to these microorganisms. We studied only for antibodies titled Cytomegalovirus (CMV), Treponema pallidum and Human Immunodeficiency Virus, and Condyloma acuminatum by cervical cytology. In 85 adolescents we found 5 (6%) patients with C. trachomatis, four of these patients had another microorganism added, one with N. gonorrhoeae, M. hominis and U. Urealyticum, one with U. urealyticum and the last two with M. hominis and U. urealyticum, In relation to Mycoplasmas 69 (81%) out of 85 had Mycoplasmas, 4 (5%) had M. hominis, 46 (54%) U. urealyticum and 19 (22%) patients had both. The seropositivity to CMV was 96.25%. We didn't find any other microorganism. We concluded that the rate of STD in chilean pregnant adolescent women is high, especially with no traditional bacteria.
